I have a comment rather than a question. I've been using cycle computers since the late 1970's with the first Avocet model.came out. I have used a variety of brands including Sigma (even on my motorcycle). I'm saying this to let you know that I'm experienced with the computers. I can't for the life of me follow the manual. I realize the international sales and the need to offer it in a wide variety of languages. Why on offer instructions one chapter at a time in each language? Or offer the instructions in each language on the website? I find the current format impossible to follow.
